[PATCH 03/12] dt-bindings: display: mediatek: add EXDMA yaml for MT8196

[Paul-pl Chen (陳柏霖)]

Hi Rob
Thanks for the advice.
The root cause of the erroneous log message is due to missing power/clock dependencies.
Once the MTK clock/power header file is upstreamed, 
we will include a reference link in the next version of the upstream series submission.
 
Best, Paul-pl Chen

My bot found errors running 'make dt_binding_check' on your patch:

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250110123835.2719824-5-paul-pl.chen@mediatek.com

The base for the series is generally the latest rc1. A different dependency should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.
